Personally, I think that one of the most exciting parts of the musical experience is that huge ensemble dance break. Shows like Something Rotten! are known for their choreography and dance breaks and personally, I think that they are one of the best moments.
But what about musicals like Les Misérables that don’t have huge dance numbers (except for some waltzing)?
Well, clearly, Les Misérables has been successful without the dance numbers. And really, if there were dance numbers, it would throw off the mood.
There is a time and place for dance breaks. Sometimes it’s going to work really well for the story that you’re telling. Other times? Not so much.
